1402(3)综采工作面压架原因分析

A Case Study of Support Break-off at 1402(3) Fully Mechanized Mining Face

1402(3)回采工作面(缩小防水煤柱开采的首采面)在开采过程中,先后出现2次综采压架事故,通过对该面综采压架原因多角度的分析研究,认为在目前的装备条件和管理水平下,上提阶段工作面完全可以采用综采回采,为指导今后潘谢矿区上提阶段回采工作面的安全生产工作提供了依据。

During the mining of 1402(3) production face (the first face of water prevention pillar reducing), two fully mechanized mining support break-offs were happened one after another. Through studies from different point of view on causation of the break-offs, the authors think under the current equipment condition and level of management, fully mechanized mining production can be used in above-mentioned stage working faces. Provide a basis of safety in production in above-mentioned faces in Panxie mining area.
